たことを特徴とする画像形成装置。[Claims for Utility Model Registration] A toner image is formed on a recording paper by an electrophotographic process, and the toner image is formed by passing the recording paper through a fixing unit having a fixing roller and a pressure roller that are in contact with each other with a predetermined pressure. In an image forming apparatus that fixes and prints on recording paper, a movable guide plate that approaches and separates from the fixing roller is provided behind the contact portion between the fixing roller and the pressure roller, and when the movable guide plate separates from the fixing roller. A first paper ejection path, which is a normal paper passing path, is formed;
An image forming apparatus characterized in that when the movable guide plate approaches the fixing roller, a second paper discharge path is formed along the fixing roller.
